Gas Detector Sensor Module Air Quality and Hazardous Gas Detection Sensor MQ-135 MQ Series Starter Kit Co Gas Sensor

– Gas Detection Sensor Module
– Quick response and recovery characteristics
– Dual signal output: analog output and TTL output
– Analog output increases with the concentration of gases, higher concentration corresponds to higher voltage
– Highly sensitive to sulfide, benzene vapor, smoke, and other harmful gases
– Signal output indication
– TTL output provides a valid low-level signal (signal light turns on), suitable for direct connection to MCU (Microcontroller Unit)
– Analog output voltage ranges from to 5V, with higher concentration resulting in higher voltage
– High sensitivity and good selectivity to carbon monoxide
– Long service life and reliable stability
